Billing software for service businesses

Services carry SAC codes, retainers repeat monthly, and getting paid on time is the whole problem. All three in one place.

The problem

Invoices go out late and get paid later

  • Monthly retainers get re-typed every cycle
  • Chasing payment is manual and inconsistent
  • Service classification and SAC codes are applied loosely
  • Reverse charge on some services is easy to miss
How BillKr fits

What BillKr does for professional services

Every capability below is in the product today — nothing here is on a roadmap.

Services as first-class items

Items can be typed as services, carrying their SAC code and rate so classification is stored once rather than decided per invoice.

Recurring invoices for retainers

Standing monthly engagements raise their own invoice on schedule instead of being re-keyed.

Receivables with ageing

Client ledgers show what is outstanding and for how long, with payment reminders that go out for you.

Reverse charge flagged on the invoice

Where tax is payable on reverse charge, the invoice says so — a mandatory particular that is easy to overlook.

FAQ

Professional Services: common questions

Does it handle SAC codes for services?+

Yes. Items can be defined as services and carry a SAC code and rate the same way goods carry HSN.

Can I automate monthly retainer invoices?+

Yes. Recurring invoices raise themselves on a schedule, so a retainer does not need re-keying each month.

Can I chase overdue payments?+

Client ledgers show outstanding invoices with ageing, and payment reminders can go out automatically.
