Invoicing, Quotation & Financial Management

Quote it, invoice it, get paid for it. All in one place.

Quotations, invoices, expenses, and financial control in one connected system. Solonomous turns an approved quote into a tax-compliant invoice, matches every payment back to it, and keeps your books, your tax position and your cash forecast current without anyone rekeying a number.

Why finance teams choose Solonomous

One ledger of truth for quotes, invoices, expenses and cash.

  • One record from quote to cash

    A quotation, its revisions, the invoice it became, the expenses booked against it and the payment that cleared it are the same record — not five. Pull the deal in from CRM & sales, route the spend through procurement approvals, and finance never reconciles two systems by hand again.

  • Tax compliance built in, not bolted on

    GST slabs, VAT treatment, reverse charge, TDS and place-of-supply rules are applied when the document is created. Credit notes carry the original tax treatment, and every filing period exports in a format your accountant already accepts.

  • Approvals that actually move

    Discount thresholds, credit limits and expense caps become rules rather than emails. Escalations, delegations and out-of-office cover are handled by automation systems, and approvers act from a single portal instead of a mailbox.

  • Get paid sooner, chase less

    Ageing buckets update live, reminders go out on the schedule you set, and every promise-to-pay is logged against the invoice. Collections stops being a spreadsheet somebody owns and becomes a queue the whole team can see.

  • Cash-flow visibility you can act on

    See committed spend, open quotations, unbilled work and expected receipts on one timeline, then push the same figures into analytics and reporting so the board sees the position finance already knows.

  • An audit trail nobody has to assemble

    Every edit, approval, tax change, write-off and credit note is stamped with who, when and why, and the document numbering series cannot be broken. When the auditor asks, you filter — you do not go looking.

    One finance hire, not five

    Scale billing without scaling headcount

    Recurring schedules, automated reminders and rule-based approvals absorb the volume, so a growing order book does not mean a growing finance team.
