# Invoicing & billing for saas & startups

Invoicing & billing for SaaS & startups runs through a billing system, but the billing system does not run itself: plan changes need proration, enterprise contracts need custom invoices with PO numbers, usage-based fees need the metered data pulled and checked, and failed payments need dunning that does not churn the customer. Our billing desk operates Stripe Billing, Chargebee, Recurly or Maxio on your behalf, raises manual enterprise invoices from signed order forms, checks usage invoices against the metered export, applies credits and proration correctly and reconciles every invoice to QuickBooks Online or Xero.

## How it runs for SaaS companies and venture-backed startups

BillingLine answers customer billing questions under your brand.

## What are outsourced invoicing services?

Outsourced invoicing services mean a remote billing team prepares, checks and sends your customer invoices instead of your office staff doing it between other tasks. The team works inside your accounting or billing software, follows your rate cards and contract terms, and issues credit notes and corrections. You keep control of pricing, approvals and the customer relationship.

## What we handle for SaaS companies and venture-backed startups

- Raise enterprise invoices from signed order forms with PO numbers and payment terms
- Check usage-based invoices against the metered data export before sending
- Apply upgrades, downgrades and proration in Stripe Billing or Chargebee correctly
- Issue credit notes for service credits and contract changes with the reason recorded
- Sync every invoice and credit to the ledger and reconcile monthly

## The KPI that matters here

100% of enterprise invoices issued within 2 business days of the order form and usage invoices reconciled to metered data before release.

## SaaS compliance notes

### ASC 606 and IFRS 15 revenue recognition

Revenue is recognized when performance obligations are satisfied: subscriptions ratably over the term, usage as consumed, implementation fees over the period your accountant determines, and multi-element contracts allocated on standalone selling prices. We apply the policy your CPA or auditor sets and document the judgment for each contract type. Investors and acquirers expect this from the first institutional round.

### Deferred revenue and contract liabilities

Cash collected ahead of service is a contract liability, not income, and the balance must roll forward every month: opening, billings, revenue recognized, closing. We maintain that schedule by customer and contract and tie it to the balance sheet and to the billing system, which is the first thing a diligence team tests.

### Sales tax, VAT and GST on software

SaaS is taxable in a large share of US states and subject to VAT or GST on digital services in the UK, EU, Canada and Australia, each with its own registration threshold. We track taxable sales by jurisdiction, configure Stripe Tax, Avalara or TaxJar where you use them, and prepare filing workpapers for your tax adviser. We do not provide tax advice or file returns; your adviser or registered agent does.

### SaaS metrics and investor reporting

MRR, ARR, gross and net churn, net revenue retention, CAC payback and burn multiple are reported from reconciled billing and ledger data with definitions documented. Board decks, lender covenant reports and data-room packs use the same figures as the monthly close, so nothing needs restating at the next round.

## Frequently asked questions

### Can you manage our Stripe Billing or Chargebee account?

Yes, we operate the billing system day to day: creating and amending subscriptions from signed order forms, applying proration on plan changes, issuing credits, configuring dunning emails and running the invoice reconciliation to the ledger. Pricing and plan design remain your decisions. Access is scoped so we cannot change payout accounts or move funds.

### How do you handle mid-cycle upgrades and downgrades?

Proration is applied in the billing system according to your policy, either immediately or at the next renewal, and the resulting invoice or credit is posted to deferred revenue and recognized over the remaining term. We check that the billing system's proration matches the contract and that the deferred revenue schedule moves with it. Downgrades and cancellations feed the churn calculation.

### What about invoices for enterprise customers who do not pay by card?

Enterprise customers usually pay by ACH or wire on net-30 to net-60 terms against an invoice with their PO number. We raise those invoices from the order form, submit them to the customer's AP portal where required and track them through the accounts receivable cadence. The invoice is still posted to deferred revenue and recognized over the contract term.
