Before your first invoice
Two screens decide whether your documents come out right.
- Settings → Workspaceholds your registered legal name, address, tax registration and the logo that prints on the document. Indian workspaces set the GSTIN and GST state here, and that's what decides how tax splits.
- Finance → Products holds what you sell, with price, tax rate and HSN or SAC code. Lines pull from here onto quotes and invoices, and the codes carry through to your filing summaries.
Customers live in Finance → Customers. Set each one's state and tax registration on their record so tax is worked out rather than remembered. Customers who aren't registered, or who are exporters, can be marked as such once instead of being handled invoice by invoice.
Invoices
Raise one from Finance → Invoices, or convert an approved quote and keep the lines, tax treatment and customer.
Numbering follows your financial year and runs in sequence. Tax is split into CGST and SGST within your own state, and IGST outside it, from the states on the two records.
The layout, accent colour, default notes and terms come from Settings → Document Templates. Send it by email from the invoice, or download the PDF.
Getting paid
Add a payment link
Connect Razorpay in Settings → Integrations and your invoices carry a payment link. When the money lands, the invoice is marked paid and the balance updates on its own.
Or record it yourself
Paid by transfer or cheque? Record the payment against the invoice. Part payments are fine, and the balance carries.
Chase what's late
Finance → Collectionslists everything outstanding, oldest first, with what's been chased and when. It's the one screen to work down on a Friday afternoon.
Recurring. A retainer or subscription is set up once from an existing invoice as its template, and raises itself from then on.
Credit notes
Issue a credit note against an invoice when you need to refund, cancel or correct something after it's gone out. It carries the original's tax treatment, and it's deducted from revenue in your reports and your tax summary rather than being edited away silently.
Money going out
Two different things, deliberately kept apart.
- Expense claims are what your people spend and want back. File one in Finance → Expenseswith the receipt attached. It goes to an approver, and you're notified when it's decided. You see your own claims. Approvers see their team's.
- Vendors and bills are what your suppliers invoice you. Finance → Vendors holds the supplier and its terms, Finance → Billsthe invoices they send you and what you've paid against them.
They're separate modules on purpose. Being able to file a claim shouldn't let someone read every supplier's terms and the company's outstanding payables.
Reports
Finance → Reportshas three tabs: a profit overview, A/R aging, and a cost breakdown. You get revenue and profit for the year and month to date, a twelve-month revenue against costs chart, your top customers, what's owed to you by how late it is, and where the money went by category. Export gives you the twelve-month series as a CSV.
It's a cash basis view.Revenue counts payments you've actually received, net of tax and credit notes. Costs count approved and paid expense claims plus the cash you've paid against supplier bills. An unpaid bill sitting in the system doesn't move your profit until you pay it.
Tax filing
Finance → Tax Filing builds the numbers for one month at a time: tax on what you sold, input credit on what you bought, and the net payable or credit carried forward. Underneath sit an HSN and SAC summary and your B2B outward supplies, each exportable as a CSV.
These are working summaries for you or your accountant to file from. They're not an upload file for the tax portal, and OSLO doesn't file on your behalf.
Invoices only appear in the B2B list when the customer's tax registration is on their record, which is the usual reason a figure looks light.
Billing in another currency
Your workspace bills in one currency, set in Settings → Workspace. An individual invoice can be raised in a different one. When it is, the exchange rate is shown on the invoice and you can edit it before saving.
That rate is then frozen onto the document. Later movement in the market doesn't rewrite history, and reports convert everything to your own currency at the rate each document was raised at.
