Twenty late-night invoices.
One cold coffee.

Renewals, seat changes, and proration: all checked manually before the invoice can go out, and it all starts again next month.

We were managing subscriptions in spreadsheets and dreading billing day. Saasybill made it something that just… happens.

You've outgrown spreadsheets.
You haven't outgrown Xero.

There's a gap between “manual invoicing on the side” and “the enterprise platform that owns your stack.” That gap is exactly where Saasybill lives.

i. Manual

Spreadsheets &
repeat invoices

Manageable at first. Then subscriptions change mid-cycle, customers upgrade, and the spreadsheet stops making sense. Someone is reconciling proration on a Tuesday night.

  • Manual invoice creation
  • No proration logic
  • Numbers drift

ii. The middle

Saasybill
sits on Xero

  • Five billing models
  • Day-accurate proration
  • Accurate revenue reporting
You are here20–250 customers
iii. Enterprise

Enterprise billing
owns the stack

Powerful, but invoicing leaves Xero. Your accountant sees a summary. Reconciliation gets weird. You pay a percentage of every dollar.

  • Transaction fees
  • Revenue lives elsewhere
  • Complex onboarding
The overkill500+ customers

Your source of truth stays your source of truth.

Most billing tools own your invoicing. That's how transaction fees work. Every invoice Saasybill creates is a native Xero invoice. Same sequence, same reports, nothing to reconcile.

  • i.
    Nothing lives outside Xero
    Invoices land in Xero the moment they are created. No sync jobs, no exports, no second system to check.
  • ii.
    Every Xero field, fully populated
    Line items, tax codes, payment terms. All set natively, indistinguishable from an invoice you made by hand.
  • iii.
    Reports that need no fixing
    Aged receivables, GST returns, cash flow. All accurate in Xero from the moment an invoice is created, with nothing to reconcile.

Everything subscription billing
actually needs.
