The individual freelancer pays your invoice without reading it. The eight-seat corporate account does not. It goes to a finance team you have never met, gets checked against a purchase order you were never sent, and either enters an approval queue or comes back with a one-line rejection that explains nothing. Meanwhile the member sitting on your floor has no idea any of this is happening and neither do you, until day forty when you ask about payment.
This is the quiet asymmetry of coworking. Your largest and stickiest revenue comes from companies, and companies buy differently from people. They are not evaluating your community events. They are evaluating whether the document you sent lets them book the expense and claim the input tax credit on it. Get the document right and a corporate account is the easiest money in the building. Get it wrong and you spend a quarter chasing a client who genuinely believes they have paid you.
Why a corporate desk contract is a B2B sale, not a membership
A member is a person who works at your hub. A corporate account is a company that buys capacity there, and everything about the transaction is different — who signs, who pays, when they pay, and what has to be true of the paperwork before they can.
The practical implication is that the member record and the customer record are not the same thing. Rohit sits at desk 14. The customer is his employer, with its own legal name, its own registered address and its own GSTIN, which may well be in a different state and almost certainly does not match the address on Rohit's ID.
If your system only knows Rohit, you will eventually raise an invoice to Rohit for a company's seats, and it will be rejected — correctly. So member profiles need a type: individual or corporate, with the corporate ones carrying the entity name and GSTIN that every invoice, booking and reminder then hangs off. That single field is the difference between a smooth account and a recurring monthly argument.
GSTIN on file before the first invoice, not after
Collect the GSTIN during onboarding, alongside the entity name exactly as registered, and the registered address. Not after the first invoice bounces. There is no polite way to ask a client to accept a corrected invoice for a month that has already closed in their books, and there is no way at all to add a GSTIN retrospectively to a document that has already been reported.
Four details are worth getting right on day one, because they cost nothing then and are painful later.
- The legal entity name, not the brand. The company everyone calls by a short trading name is usually registered as something longer with a Private Limited on the end, and the finance team will match on the registered name.
- The GSTIN that corresponds to the state and place of business the client wants to claim from — a group with registrations in several states will tell you which one, and it is not always the one nearest you.
- A billing contact who is not the member. The person at the desk is not the person who pays, and every reminder you send to the wrong one is a week lost.
- A purchase order or reference number if the client uses them, captured at onboarding, because an invoice without it will sit unprocessed and nobody will call to tell you.
Store all of it against the member record itself so that it flows onto every document automatically. A GSTIN that lives in a WhatsApp message from March is a GSTIN that will be mistyped in September.
What has to be on the invoice for the client to claim credit
A tax invoice is a prescribed document, not a formatted bill. The particulars are set out in the GST rules and a finance team checks them mechanically, which is good news — it means the requirements are knowable and repeatable rather than a matter of taste.
- Your name, address and GSTIN as the supplier
- A consecutive serial number, unique within the financial year — this is the one operators break most often
- The date of issue
- The recipient's name, address and GSTIN
- A description of the service, with the applicable SAC classification
- Taxable value, the rate of tax and the tax amount, with CGST and SGST shown separately where that is the applicable split
- The place of supply
- Signature or digital signature of the supplier or an authorised person
The place-of-supply line is the one that generates the most confusion in coworking, because a hub in one state routinely sells to a company registered in another. Whether your invoice carries CGST and SGST or IGST follows from the place-of-supply rules, and for a service tied to a physical space the answer usually points at the location of the space rather than the address of the customer. That has a direct consequence for your client — it determines whether the credit is usable to them at all — which is exactly why their accountant will ask. Get the position confirmed once by your own accountant for the way you actually operate, write it down, and then apply it identically to every corporate account. Inconsistency across invoices is what triggers scrutiny, more than any single treatment.
Your member decides to join. Their accountant decides whether you get paid on time. Only one of those two people ever reads your invoice.
Membership, booking and amenity lines: bill them separately
The temptation with a corporate account is to send one clean number — eight desks, a monthly figure, done. Resist it. A single-line invoice is the hardest kind for a client to process, because their finance team cannot map it to anything and their internal cost allocation has nowhere to put it.
Break the invoice into the things you actually supplied. The membership itself, by plan and period. Meeting-room bookings that ran beyond what the plan included, with dates. Amenities — lockers, parking, printing, cafe credits — as their own lines. Any one-off charges named plainly.
Three things improve at once. The client can allocate the cost internally without asking you for a breakdown, which removes a week from the cycle. Disputes narrow to one line instead of the whole invoice. And you get a revenue picture by category, so you can finally see whether amenities are a business or a courtesy.
It protects the renewal too. A client who has seen twelve itemised invoices knows what they bought and what they used. A client who has seen twelve identical lump sums treats renewal as a fresh price negotiation, because there is nothing in front of them but a number.
Gap-free numbering, and the month a missing number gets noticed
Invoice numbers must run in a consecutive series, unique for the financial year. Not roughly consecutive. Not consecutive per client. One series, no holes.
The way hubs break this is never deliberate. Somebody raises an invoice, the member says wait, we are changing the plan, and the invoice is deleted. Somebody else keeps a separate book for cash day passes with its own numbers starting at one. A manual invoice gets typed in Word for a client in a hurry and never enters the sequence at all. Each of these is a five-second decision that creates a gap.
The gap surfaces at the worst possible time — during a reconciliation, an audit or a client query — and it is unanswerable after the fact, because the honest explanation is that somebody deleted a document and nobody recorded why. The fix is structural rather than disciplinary: numbers should be issued by the system, never editable, never reused, and a cancelled invoice should be cancelled rather than deleted, so the number stays in the series with a visible reason attached.
Day passes and cash sales belong in the same series as everything else. A parallel receipt book is the most common source of both missing numbers and untracked revenue, and it is usually invented by a well-meaning receptionist trying to be quick.
Pauses, upgrades and mid-cycle changes: credit notes, not edits
Coworking is full of mid-cycle change. A member upgrades from three desks to five on the 12th. A team pauses for two months because a project ended. A plan gets downgraded after a headcount cut. Every one of these creates the temptation to open last week's invoice and change it.
Do not. An issued invoice is a filed document, and if it has been reported, editing it puts your records and your client's out of alignment in a way that surfaces in their reconciliation and not in yours. The correct instrument for reducing an already-issued invoice is a credit note, which references the original, states the reason, and is itself a numbered document. An increase is a fresh invoice for the additional supply.
There is also an outer date beyond which a credit note can no longer adjust your tax liability for a past financial year. It is generous rather than immediate, but it is real, which is the whole argument for never letting a disputed month drift. Ask your accountant what the current cut-off is and then treat any open credit note older than a quarter as a problem, not a to-do.
Practically, this means a membership needs pause, renew and expire as first-class actions with dates against them, rather than a plan field that somebody overwrites. The billing history has to survive the change, because in eighteen months a client will ask why they were charged a particular amount in a particular month and the only acceptable answer is a document.
Advance payments and security deposits are different documents
Corporate accounts frequently pay ahead — a quarter upfront for a discount, or a deposit against a private cabin. These are not the same thing and they must not be recorded as the same thing.
An advance is money against a supply you are going to make. When you take money for services before supplying them, the GST rules require a receipt voucher for the advance, and the tax treatment follows the advance rather than waiting for the invoice. The invoice then follows at the point of supply, adjusted against what was received.
A refundable security deposit is different in kind. Under GST law a deposit given in respect of a supply is not treated as payment for that supply unless and until the supplier applies it as consideration. So it sits on your books as money you hold, not money you have earned — and on the day you do apply part of it against dues or damages, that portion changes character and has to be documented accordingly.
Mixing the two is a genuine liability. Recording an advance as a deposit understates what you owe in tax; recording a deposit as revenue overstates your income and leaves you with a refund obligation that appears nowhere in your numbers. Both are found in year two, by an accountant, in a bad week.
The reconciliation your member's finance team runs on you
Here is the part most operators never see. Periodically, your client's accountant compares the credit they have claimed against what suppliers have actually reported. If your invoice is missing from that comparison, or the value differs, or the GSTIN is wrong, the client's credit is at risk — and their response is to hold your payment until it is fixed.
Which reframes the whole subject. Invoice hygiene is not a compliance chore that sits downstream of the business; it is a collections mechanism. Every avoidable defect in your paperwork converts directly into days of delay in your bank account, and the client never explains why, because from their side it is obvious.
- GSTIN and legal entity name captured at onboarding and reused, never re-typed
- One consecutive invoice series, gap-free, with cancellations recorded rather than deleted
- Every invoice itemised by membership, bookings and amenities, with dates
- Corrections issued as credit notes referencing the original document
- Advances and refundable deposits recorded as different things
- A pay-link on the invoice itself, so approval and payment are one step rather than two
- A dues board by member, so an unpaid corporate account is visible in week one rather than at renewal
The last two are where recurring revenue actually becomes recurring. A membership on a UPI AutoPay mandate collects itself on its due date for the members who can use it; for the corporate accounts that pay by transfer against approval, a shareable pay-link on a correct invoice is the shortest path between their approval queue and your account. Everything above exists so that nothing in that path can stall.
None of this makes your hub more attractive. It makes it easier to buy from, which for a corporate account turns out to be the same thing.
