How to create an invoice for a gym member, with GST
Bill a membership plan or sell a product with Create Invoice: pick the member, dates, tax and coupon, and record the payment in the same step if they've paid.
Every rupee your center collects should have an invoice behind it. Fitnexa has two kinds: a Plan invoice bills a membership and updates the member's membership dates, and an Inventory invoice sells products such as a protein shake or a pair of gloves.
If the member pays at the desk right away, you can record the payment while you create the invoice, so it goes straight to PAID.
Step by step
Open Invoices
Click More in the left-hand menu, then Invoices under Finance. Click Create Invoice at the top right.
In the Admin menu, open More, then select Invoices.
Choose the invoice type
Under Invoice type, pick Plan — bill a membership for a new or renewed membership, or Inventory — sell a product for counter sales.
Then choose the Member. For product sales you can leave it as Walk-in / none. Set the Billing country, Issue date and Due date.

Plan invoice: choose the Plan, then check Membership start — it defaults to the day after the member's current membership ends, or today. Membership end follows from the plan's length and can't be edited. The invoice adds the membership to the member's record as Awaiting payment; it becomes Active once the invoice is paid. Renew on a member's profile opens this same form with the member already chosen.
Inventory invoice: under Line items, enter a Description, Qty and Unit price, or use + Inventory item… to pick a product from stock (stock goes down automatically) and + Enrolled service… for a service the member is enrolled in. Click Add line for more rows.

If the member is paying right now, tick Record a payment and click Next: Payment. Enter the Paid amount, Method, Date and, for UPI or card, the Transaction ID. Click Create Invoice & Record Payment.
If they'll pay later, leave it unticked and create the invoice. Tick Remind me to collect this payment and pick a date in Remind me on so it shows up in Reminders.
For a plan invoice that isn't paid in full, Fitnexa asks The invoice is unpaid. Activate the membership now? Yes makes the membership active straight away — it shows Active — invoice unpaid until the invoice is paid (needs Manage members & memberships). No leaves it Awaiting payment until the invoice is paid.

If something goes wrong
- Membership needs a member, plan, and start date
- A plan invoice must have a Member, a Plan and a Membership start. Walk-in isn't allowed for plans — register the person first.
- Add at least one line item
- An inventory invoice needs at least one row with a description, quantity and price.
- Paid amount exceeds the invoice total (…)
- The payment can't be more than the invoice. Lower the Paid amount to the total or less.
- Invalid coupon
- Check the spelling, and in Promotions check the coupon is enabled, not expired, and that the invoice meets its minimum amount.
- Not enough stock for Whey Protein 1kg (have 2).
- Lower the quantity, or add stock to the item in Inventory & Assets first.
Common questions
Can members pay their Fitnexa invoice online?
No. Members pay at your front desk by cash, card, UPI or bank transfer, and you record the payment on the invoice. Members can see and download their invoices in their account.
Does a plan invoice renew the membership?
Yes. It adds a new membership from Membership start to Membership end to the member's record. It goes live when the invoice is paid, or straight away if you choose to activate it.
Can I create an invoice from the mobile app?
Yes. On a member's profile, open Invoices and tap Create invoice, then choose Inventory (products, if you can view inventory) or Plan. As on the web, typing your own prices, a discount or recording a payment needs Manage billing.
How do I give a membership for free?
Don't raise a zero invoice — use Give complimentary membership on the member's Membership tab. It needs Manage members & memberships and Manage billing, and a reason.
How do I add GST to an invoice?
Set a Tax Rate (%) on the membership plan and it's applied automatically. You can change Tax rate (%) on any single invoice.
