Best billing tools for agencies reselling software
Reselling a subscription to a client means billing for it, usually with a markup. Most billing tools price by a percentage of the volume moving through them.
Stripe Billing wins as the default starting point for most agencies, since it prices by volume rather than a flat monthly fee, which fits a reselling business whose billed amounts vary by client.
The short answer
- Stripe Billing's pay-as-you-go pricing is roughly 0.7% of billing volume with no recurring subscription charge, or from about 0.67% on committed monthly plans with discounts for annual commitments.
- This is a percentage-of-revenue model, not a flat per-invoice or per-seat fee, so the actual monthly cost scales directly with how much an agency bills through it.
- Whether a billing platform cleanly supports reselling or sub-billing another vendor's SaaS product specifically is a configuration and contractual question, not a feature every billing tool documents plainly; confirm the exact flow you need before committing.
- Billing tooling and the underlying software subscription being resold are separate questions; check the reselling terms of the software itself before assuming any billing tool clears you to mark it up and resell it.
How we compared these
We checked the pricing model, percentage-of-revenue versus flat fee, on the vendor's own pricing page, since that is the number that determines real cost for an agency whose billed volume varies by client and month. Facts checked on vendor pricing pages, September 2026.
Billing tool comparison
| Tool | Pricing model | Approximate rate | Reselling support | Best for | Not for |
|---|---|---|---|---|---|
| Stripe Billing | Percentage of billing volume | About 0.7% pay-as-you-go, lower on committed plans | General subscription billing; specific reselling/sub-billing flows depend on configuration, not confirmed generically here | An agency whose billed volume varies by client and wants a variable-cost billing tool | An agency that wants a fixed, predictable flat monthly billing fee |
| Chargebee | Hybrid: flat fee plus percentage of volume | Flow plan: $0 plus 0.80% under $20k monthly invoicing volume, or $99/mo plus 0.65% at higher volume | Built for subscription billing broadly; multi-entity and account-hierarchy features on Enterprise, relevant to an agency billing many client entities | An agency managing several billing entities that wants hierarchy features Stripe Billing does not name explicitly | An agency that wants the simplest possible pure-percentage pricing with no flat base fee |
| Recurly | Starter $249/mo plus 0.9% of billing volume, first $40k/mo included free; All-Access from under 1% of volume, $1M minimum annual billing | Flat base fee plus percentage, or pure percentage at higher volume | Multicurrency, SSO and payments orchestration on All-Access, useful for a larger multi-client agency | A mid-to-larger agency with enough billing volume to justify the flat base fee | A small agency below the volume where the flat fee makes sense versus pure-percentage pricing |
| GoHighLevel SaaS Mode | Included at Agency Pro, $497/mo | Bundled into the platform fee, not sold as a standalone billing product | Built specifically for agencies reselling GoHighLevel sub-accounts to clients, automated account creation on payment | An agency already reselling GoHighLevel itself as its product | An agency reselling a different software product; this billing flow is built around GoHighLevel accounts specifically |
| Maxio | Pricing on request; aimed at B2B SaaS billing, not published as a flat figure | Quote-based | Built for usage-based and subscription B2B billing at scale | A larger agency or software reseller with complex usage-based billing needs | A small agency that wants a self-serve published price without a sales call |

The field, ranked
1. Stripe Billing
A percentage-of-volume model that scales with actual billed revenue rather than charging a flat fee regardless of usage. Not for an agency that wants a predictable flat monthly cost independent of revenue.
2. Chargebee
A hybrid flat-fee-plus-percentage model, with multi-entity and account-hierarchy features named specifically on its Enterprise tier. Not for an agency that wants the simplest possible pricing with no base fee at low volume.
3. Recurly
A flat base fee plus a lower percentage than pure pay-as-you-go models, worthwhile once volume clears the included free tier. Not for a small agency below the volume where the flat fee makes sense.
4. GoHighLevel SaaS Mode
Billing built specifically for agencies reselling GoHighLevel's own platform to clients, bundled into the Agency Pro plan. Not for an agency reselling a different software product entirely.
5. Maxio
Built for complex B2B usage-based billing at scale, sold through a sales conversation rather than a published price. Not for a small agency that wants a self-serve price with no sales call.
When none of these is the answer
An agency billing a handful of clients manually through invoices, with no recurring subscription structure to automate, does not need dedicated billing software. This category earns its place once an agency is running recurring subscription billing across enough clients that manual invoicing becomes real monthly overhead.
Questions
- What is different about billing for a reselling agency versus a normal SaaS vendor?
- A reselling agency typically needs to bill a client for a marked-up bundle, its own service fee plus the underlying software cost, sometimes across multiple sub-accounts. That is a slightly different shape than a single-product SaaS company billing its own direct customers, and not every billing tool handles the reselling layer cleanly.
- Does Stripe Billing charge a percentage of revenue or a flat fee?
- A percentage of billing volume: pay-as-you-go starts around 0.7% of billing volume with no recurring charge, dropping slightly with committed monthly or annual plans. It is not a flat per-seat or per-invoice fee.
- Do I need a separate tool if I am reselling SalesCrew or another SaaS product to clients?
- It depends on how you want to bill. Stripe Billing handles subscription billing generally; whether it cleanly supports marking up and re-billing a specific product's own subscription is a configuration question, not something confirmed generically here. Check the specific reselling flow you need directly against Stripe's own documentation.
- Does SalesCrew have its own billing for agencies reselling it?
- Disclosure: SalesCrew is our product. Its own billing runs on Stripe Checkout and Customer Portal for direct subscriptions. A separate agency wholesale or partner-reselling billing model is not confirmed as shipped; check current terms before assuming a resale program exists.
