The verdict in three sentences

Turning an internal reporting tool into a white-label SaaS costs between 70,000 and 130,000 USD in Miami in 2026, with a 5-month timeline to the first paying agency. With subscriptions of 89 to 229 USD a month, a realistic goal is MRR of around 9,000 USD at 18 months, roughly sixty client agencies. The federal R&D tax credit lowers the net bill, but success depends above all on reliable Google Ads, Meta and GA4 connectors.

What changes between an internal tool and a SaaS

An in-house tool tolerates workarounds. A SaaS sold to other agencies requires data isolation, automated billing and brand customisation.

The total falls between 67,000 and 127,000 USD. Add 500 to 1,500 USD a month for infrastructure, storage and API quotas depending on the number of connected accounts.

Business model and MRR projection

The reporting tool market (AgencyAnalytics, DashThis, Swydo) charges between 50 and 450 USD a month. Targeting US agencies of 3 to 20 people, with bilingual English and Spanish reports for Miami's Latino market, is a genuine angle.

PlanMonthly priceAgency clients includedTarget share of subscribersMRR contribution at 18 months

Add-ons15 to 35 USDPremium connectors30% of accountsAbout 850 USD

With 3% monthly churn, you need to sign 4 to 5 new agencies a month to hold this trajectory. These figures are a 2026 estimate, not a guarantee.

Funding: R&D tax credit and timeline

The federal R&D tax credit (Section 41) can cover qualifying software development wages and contractor costs, typically worth 6 to 10% of qualified spend in practice, and startups with under 5 million USD in receipts can offset up to 500,000 USD against payroll taxes. Since 2025, domestic R&D costs can again be expensed immediately. On 100,000 USD of qualifying spend, expect roughly 6,500 to 10,000 USD of credit, to be confirmed by your CPA. Typical timeline: month 1, scoping and mockups; months 2 to 4, multi-tenant build and connectors; month 5, private beta with 5 partner agencies then commercial launch.

Carlos, founder of a 12-person agency in Miami, uses his in-house tool for 45 clients. SaaS development is quoted at 100,000 USD, with an estimated 8,000 USD R&D credit, for a net cost of 92,000 USD. Infrastructure: 1,000 USD a month. At 18 months, with 60 agencies and about 9,130 USD of MRR, monthly gross margin reaches around 8,000 USD. Break-even arrives around month 28 after launch, accounting for the gradual ramp-up of subscribers. The agency also builds a sellable asset, often valued at 3 to 6 times annual recurring revenue.

FAQ

How much does a white-label SaaS cost in 2026?

Between 70,000 and 130,000 USD for a market-ready multi-tenant version with Google Ads, Meta and GA4 connectors. An MVP without full white-labelling can start around 50,000 USD.

Does the R&D tax credit apply?

Usually yes for new software involving technical uncertainty and experimentation. In practice it is worth 6 to 10% of qualified spend, and you need contemporaneous documentation of the work.

What subscription price should we set?

A 89 to 229 USD monthly range matches the US reporting tool market. Offer a 14-day free trial and a 15 to 20% discount for annual billing.

Who owns the code?

Your agency, entirely. Kolonell hands over source code, documentation and infrastructure access, with no royalty on your revenue.

What happens if Google or Meta change their APIs?

It is the main risk of a reporting tool. A maintenance contract of 800 to 1,500 USD a month covers these updates, usually 2 to 4 a year.
