Section 1
The 72% is real, and it is not what you think
First, get the number right, because a misused statistic is worse than none. The 72.3 percent figure is the 2017 round of the World Bank Enterprise Surveys for Paraguay. The series has a clear trend: 76.7 percent of firms competing against unregistered rivals in 2006, 75.3 percent in 2010, 72.3 percent in 2017, and 54 percent in the 2023 profile, based on 378 firms interviewed between June 2023 and February 2024. The pressure is real and regionally high, but in Paraguay it is easing, not worsening. Anyone selling you the 72 as a fresh crisis is quoting a vintage. The more useful finding is buried in the same 2023 profile, and it inverts the usual reading. Informal competition is not felt evenly. Asked to name the single biggest obstacle to their business, 14 percent of Paraguayan firms named practices of the informal sector, the fourth-ranked obstacle overall, behind corruption at 21 percent, access to finance at 18 percent, and political instability at 15 percent. But break it down by firm size and the picture sharpens. For medium firms, 20 to 99 employees, practices of the informal sector was the number one obstacle, named by 22 percent. For large firms it ranked second, at 16 percent. For small firms it did not make the top three at all; their biggest obstacle was corruption at 28 percent. Read that carefully, because it is the whole thesis in one data cut. The firms most bothered by informal competition are not the smallest. They are the ones that have already started to grow. The small firm is losing to corruption and its own thin balance sheet. The medium firm is losing to informality, precisely because it has climbed far enough that its costs are visible and its price is no longer the lowest in the room. Informal competition is a problem you grow into. Which means the way through it is not to stay small and cheap. It is to grow past the tier where the informal firm can reach you.
Section 2
The framework: why growth has a direction
No single lens explains why horizontal growth stalls and vertical growth works. Run several. The positioning lens (spatial choice). Place buyers in a space with at least two axes: price, and everything the informal firm cannot supply (recourse, a receipt, reliability, legal standing). The informal firm sits at the low-price, low-recourse corner and owns it. Horizontal growth means adding volume at your current position, which is close to that corner and constantly contested. Vertical growth means moving your position along the second axis, toward buyers who weight recourse heavily. The informal firm has no coordinates there. Growth, in this model, is literally a direction in the buyer's decision space, and only one direction is defensible. Spatial choice, the "which way is growth" lens • Assumes: buyers weigh more than price and pick the nearest viable option. • Fits because: service buyers trade off recourse and legality against cost, especially on higher-value work. • Breaks when: a segment is genuinely single-axis. Some buyers will only ever pay the lowest cash price. The model says do not chase them, and it is right. • Counteracts: the reflex to grow by adding more of the same low-margin work. • May reinforce: over-optimism about how deep the up-market is in your specific category. The pricing lens (game theory). The price war has a structural asymmetry: the informal firm carries no tax-and-compliance wedge, so its floor is lower and it wins any pure-price contest. But the equilibrium changes the instant the buyer stops treating the two offers as the same good. Bundle in a warranty, a service contract, a named-client reference, and you have moved the contest off the axis where the asymmetry favors your rival. Game theory tells you the undercut is only unbeatable while the goods look identical. Your growth job is to make them look different to the buyers who care. The threshold lens (tipping). Markets do not formalize smoothly; they tip. A sector sits at high informality and feels permanent, then digital tax infrastructure and enforcement cross a threshold and the informal discount compresses fast. Peru is mid-tip: informality fell to 70.9 percent of workers at the end of 2024, a third consecutive annual decline, per INEI, with formal employment up from 23.2 percent in 2021 to 29.1 percent in 2024. The firm that has already climbed toward formal-only demand inherits the buyers who can no longer transact in cash when the tip comes. Positioning early is how you get paid by a threshold you cannot time. Threshold / tipping, the "when does the market flip" lens • Assumes: informality responds to enforcement and digital infrastructure and can shift non-linearly. • Fits because: e-invoicing and formalization drives are live across the region. • Breaks when: a fiscal or political shock pushes informality back up. The tip is not one-directional or guaranteed. • Counteracts: treating today's informality rate as a fixed constraint. • May reinforce: premature betting on a tip that stalls for years. The structure-break flag (the governor). Every one of these models is downstream of one variable: the enforcement regime. It sets whether the informal discount is 40 percent or negligible, whether the up-market is a trickle or a flood, whether the threshold is near or distant. When enforcement moves, the direction of growth does not change, up-market is still the answer, but the urgency and the size of the prize do. Watch your country's e-invoicing mandates and formalization programs the way a contractor watches a commodity price. They are the leading indicator of how fast your escape route is widening.
Section 3
Country cuts: the same problem, four different rulebooks
The vertical-escape logic is regional, but the terrain differs by country. The numbers below are the ones that should shape where you push. Paraguay. Informal competition bites hardest at the medium-firm tier, the number-one obstacle for 20-to-99-employee firms at 22 percent in the 2023 Enterprise Survey. The same survey shows why the up-market and formal-only channels are wide open: only 7.3 percent of Paraguayan firms export directly, and 9.3 percent export directly or indirectly. Export intensity is a near-empty field, and it is one the informal firm cannot enter, because an exporter needs a registered, invoice-issuing counterparty. Real annual sales growth for surveyed firms ran 13.1 percent, so the formal sector is growing; the question is which firms capture it. In Paraguay the vertical move is toward the formal-only and export channels, where competition is thin precisely because informality disqualifies most of the field. Peru. The story is the tip in progress. Informality fell to 70.9 percent of the workforce by the end of 2024, per INEI, the third straight annual decline, with formal employment at a decade high of 29.1 percent. The productivity gap is the lever: Peru's IPE has estimated that formal workers produce several times more per head than informal ones, which means the up-market buyer who wants quality and throughput has a real reason to pay for a formal provider. Note the geography, though: urban informality sits near 66 percent while rural exceeds 94 percent. The vertical escape is viable in Lima and the coastal cities; in the rural interior the single-price axis still dominates and the honest move may be different. Colombia. Informality ran around 55.8 to 56 percent through 2024, per DANE, lower than Peru or Paraguay, but the regional spread is the story. Bogotá sits at 34.7 percent informal, Medellín at 37.6 percent, while cities like Sincelejo reach 65.7 percent. Colombia is not one market; it is a formal-leaning set of major metros wrapped around a highly informal periphery. The implication for growth is concrete: the up-market and formal-only escape is broad and real in Bogotá and Medellín, where a majority of buyers are already inside the formal system, and much narrower in the high-informality secondary cities. Pick your city before you pick your strategy. Mexico. Labor informality ran about 54.6 percent in late 2024, per INEGI, the lowest of the four, and Mexico has the region's deepest formal-only demand: a large export-manufacturing base, nearshoring supply chains, and corporate buyers who require a valid CFDI electronic invoice to deduct any expense. The e-invoicing regime is strict and long-established, which means the enforcement variable is already tightened. In Mexico the informal discount is real at the consumer edge but the formal-only channel, supplier to a registered company, is enormous and legally walled off from informal competitors. The vertical escape here runs straight into the B2B and supply-chain tier. The pattern across all four: the more formal the metro and the tighter the invoicing regime, the wider the vertical escape and the weaker the informal undercut. Growth runs toward formality, and your job is to run with it faster than your market does. One more cross-country signal worth reading before you commit capital: firm growth and export intensity move together, and both favor the formal firm. The Paraguay 2023 survey shows surveyed firms growing real sales at 13.1 percent a year while only a single-digit share export at all, which means the formal sector is expanding faster than its firms are reaching the least-contested channels. That gap is the opportunity. In Mexico, the nearshoring wave has pulled formal-only demand deeper still: a supplier feeding a registered exporter or a multinational plant is transacting in a channel where an informal vendor is not merely disadvantaged but legally inadmissible, because the buyer's own compliance depends on a valid invoice from every input. The practical read is that the size of your vertical escape is set less by your effort than by how formal your buyers already have to be. Sell into the most compliance-bound buyer you can legitimately reach, and the informal undercut stops being a factor at all.
Section 4
The response: levers, a dated portfolio, and a history check
1. The levers: climb, do not sprawl Your dominant exposure is volume growth at the price-comparable tier. Every useful lever moves you up the recourse axis instead of out along the price axis. • Segment up, on purpose. Identify the sub-set of your work where a failure is expensive to the buyer and rank it. Grow that, decline the rest. A minimum ticket size is a blunt but effective filter: it prices you out of the jobs the informal firm wins and signals a tier. • Change the contract type. Move from per-job to per-period. A maintenance agreement, a monthly retainer, a service contract with recurring billing does two things at once: it is a formal-only instrument the cash vendor cannot credibly offer, and it converts one-off price shopping into a relationship the informal firm cannot intercept. • Chase export intensity where it exists. In Paraguay and much of the region, direct exporting is a single-digit-percentage activity, which makes it uncrowded. Even indirect export, supplying a firm that exports, requires your invoice and your compliance. It is the clearest formal-only field on the board. • Build the proof only a formal firm can produce. A case study with a named client and a real invoice trail, a corporate reference, a completed tender. These are growth assets an informal competitor cannot fabricate without becoming formal, and they are the ticket into the next tier of buyer. Cheap and reversible first: raise the minimum ticket and write one service-contract offer this month. Expensive and slow later: build the export or tender pipeline. 2. The dated portfolio: grow under an uncertain regime • Do now (right in every scenario): convert one revenue line from per-job to per-period, and set a minimum ticket. Both raise margin and shed the most-contested work whether or not enforcement moves. Zero regret. • Hedge (cheap insurance against a fast tip): land one formal-only client, a company that needs your invoice, and document it as a reference. Small cost, large payoff if the market formalizes quickly and formal-only demand surges. • Defer, with a trigger (irreversible, so wait): do not build a dedicated export or government-tender capability until the signal fires. Pre-commit it: "when direct-export inquiries reach a set threshold, or when e-invoicing tightens in my sector, I staff the tender desk." Write it now. 3. The history check: what usually happens as a market formalizes Base your confidence on the reference class. Across Latin America, the direction of travel over the last decade has been toward formality where digital tax infrastructure took hold, Peru's three-year decline and Mexico's entrenched e-invoicing being the clearest cases. As markets formalize, the informal discount compresses and demand migrates to firms already positioned in the formal-only and up-market tiers. The firm that climbed early does not just survive; it collects the buyers who can no longer legally transact in cash. That is the base rate that makes vertical growth a bet on the trend, not a leap against it. The matrix-break caution stands: the trend is not guaranteed. Colombia's informality has been sticky near 56 percent for years, and a fiscal or political shock can re-widen the discount anywhere. Treat formalization as the more likely path, size your commitment to your specific city and sector, and keep the trigger written.
Section 5
What this framework cannot see
Name the blind spots. The vertical-escape thesis assumes an up-market of real depth in your category and your city. The country cuts show that depth varies enormously: broad in Bogotá and Mexican B2B, thin in rural Peru and Colombia's high-informality secondary cities. In a genuinely single-axis local market, the model's advice is honest but small: climb as far as the segment allows, and accept that the ceiling is low. The framework also leans on Enterprise Survey data that is periodic and, for some countries, several years old; the Mexico and Brazil competition figures in the World Bank series date to 2010 and 2009 respectively, so treat cross-country comparisons as directional, not precise. And it assumes your rival is fully informal; against a semi-formal under-declaring competitor that can show partial credentials, the formal-only channel is a weaker moat than against a pure cash operator.
Section 6
The fitness test
You should commit to vertical growth, up the segment, into per-period contracts, toward the formal-only and export tiers, if your city has a formal-leaning majority of buyers, your category includes work where a failure is expensive, and you can name at least one buyer who legally needs your invoice. Under those conditions the 72% problem is not a ceiling. It is a description of the tier you are leaving. You should grow horizontally and compete on operational efficiency instead if you operate in a high-informality periphery where the single-price axis genuinely dominates, with no export channel, no corporate buyers, and no meaningful up-market. That market is real, and in it the honest growth strategy is to be the leanest compliant operator you can be, or to move your business to a metro where the vertical door is open. Either way, stop treating the 72 as a wall. Read it as a map. It tells you exactly which tier the informal firm controls, which means it tells you exactly where to go next. Growth in a surrounded market has a direction, and the direction is up.
