Embedded Payments Consultancy for Vertical SaaS Companies

The problem

Vertical SaaS founders know embedded payments could double their revenue per customer, but the decision is genuinely hard. Payfac-as-a-service versus referral versus full PayFac, which provider, what the real take rate is after interchange and processing, what underwriting and compliance obligations they inherit, how to price it to merchants without a revolt. Most founders either stall for a year or sign a bad deal with the first provider that calls them.

Why now

Payfac-as-a-service offerings from Stripe Connect, Adyen for Platforms, Payrix, and Finix have made embedded payments accessible to companies far smaller than before. That has created a wave of vertical SaaS companies who now have the option but not the expertise, and providers who will happily sell them the wrong tier.

Who pays

Founders and heads of product at vertical SaaS companies with $1M to $30M ARR serving merchants who take payments (fitness studios, clinics, trades, salons, schools) in the US, UK, Canada, and Australia.

How it makes money

Fixed-fee strategy engagements $10,000 to $40,000 covering economics modelling, provider selection, and integration scoping. Follow-on advisory retainer $3,000 to $8,000 per month during launch. Do not take undisclosed provider kickbacks, because that destroys the only asset you have, which is independence.

Market & demand

Order-of-magnitude: thousands of vertical SaaS companies in this ARR band across the four markets, and embedded payments is on most of their roadmaps. Eight to twelve engagements a year at $20,000 average is a strong solo practice.

The public vertical SaaS companies that added payments (Toast, Shopify, Lightspeed) show payments revenue eventually exceeding subscription revenue. That precedent is now well known among founders, which creates demand for the how, not the why. The expertise gap is the opportunity.

SWOT

Competition & the gap

Payments providers' own solutions teams (free but conflicted), boutique fintech consultancies, big-four advisory practices (expensive and slow), and in-house hires.

The wedge: Everyone advising a founder on payments is being paid by a provider. An independent, fee-only consultant who models the real economics across providers and tells the founder the boring truth is genuinely rare and worth paying for.

Go-to-market

Publish rigorous, numbers-heavy analysis of embedded payments economics that no provider would ever publish, such as what a 30 basis point spread actually nets after chargebacks and support cost. That content is the entire funnel for this buyer.

First 10 customers: Do 3 engagements at a steep discount for vertical SaaS founders in your network, in exchange for permission to publish anonymised economics case studies. Those case studies are the marketing asset for everything after.

How to set it up

1. 1Build a rigorous payments economics model covering interchange, processing, spread, chargebacks, and support cost
2. 2Map the provider landscape honestly including where each one is genuinely better
3. 3Write the flagship analysis piece and publish it
4. 4Run 3 discounted engagements and publish anonymised results
5. 5Set fixed-fee packaging for strategy plus launch advisory
6. 6Build referral relationships with vertical SaaS VCs and operators

How to validate it

Founders arrive already having read your analysis, engagements convert without a competitive process, clients bring you back for the launch phase, and providers start (grudgingly) recommending you as the independent voice.
