How To Create And Send An Invoice in WorkZen

All plansBeginnerVideo, 2:00Updated October 17, 2026

Go to Invoices, click New Invoice, pick the client, and add your line items. Then click Send Invoice to email it; if Stripe is connected, the client can pay online right from the invoice.

Unbilled jobs are interest-free loans you didn't agree to give. Sending the invoice the same day the work wraps up is the biggest cash flow win in a service business, and in WorkZen it takes about two minutes.

Create the invoice

Go to Invoices and click New Invoice. Pick the client in the Create New Invoice modal (or use or create a new client), then click Create Invoice. You can also create invoices from a job's Finance tab, or by converting an accepted estimate.

New invoices start as Unsent. There is no separate draft state; until you send it, you can edit everything freely.

If the invoice was created from a job that has a PO number, the PO is copied onto the invoice automatically. Edit it in the invoice's Bill to section; changes there apply only to that invoice.

Add line items

In the Items section, click Add item. The Add items picker has a search box on top: leave it empty to browse your price book folders (Services, Products, Warranties), or type to search it. The Packages folder lists your bundles, and Custom item at the bottom left adds a one-off line. Pick a package and every item in the bundle lands on the invoice in one click, quantities and prices included.

Tip

Build packages once on the Price Book page and stop re-typing the same five lines on every install.

Each saved line item also takes internal comments: the small comment icon on the item's row opens a thread only your team sees. Use it for the "client wants brass, not steel" details that belong with the line, never on the document. Clients never see these comments, on screen or on the PDF.

Send it by email or text

Click Send Invoice at the top right of the invoice. At the top of the send modal, choose Email, Text message, or Both. Email shows the client's Email address and a prefilled Email message you can edit, and you can enter several addresses separated by commas. Text message shows the client's Mobile number and a prefilled Text message with a secure link to the invoice, which you can edit too: the link is always included, and if you delete it, WorkZen adds it back at the end. In the mobile apps the text goes out as your message template reads. Either way the status flips to Sent and the client lands on the live invoice page.

Texting needs a number to send from: your company's default texting line if you have a ZenPhone number, otherwise the shared WorkZen number on ZenGrow and ZenAI. On Zen with no line, the Text message option is refused with a message saying why, and email still works.

Whether your client can reply depends on which number sent it. From your own ZenPhone line the text appears in Messaging, in that client's conversation, and anything they write back lands in the same thread. The shared WorkZen number has no inbox, so the text itself tells your client that replies to it are not monitored.

If WorkZen asks you to verify a phone number by text before emailing documents, a banner walks you through it: enter the code once and you're cleared to send from then on, for your whole company.

What your client sees

The invoice your client opens has Print, Download PDF, and Share buttons. If your company has Stripe connected, it also offers Pay with Card and, when enabled, Pay by Bank. Online payments update the invoice balance automatically, and WorkZen records when the client opens the invoice.

Invoice statuses

StatusMeaningWhat you can do
UnsentCreated, the client hasn't received itEdit freely, send, delete
SentEmailed to the clientRecord payments, resend
Partially PaidSome money received, balance remainsRecord more payments
PaidFully paidView, refund
OverduePast the due date with a balance owingRecord payments, resend
VoidCancelled, no longer payableView only; totals excluded from reports

Once the money arrives, record the payment so the status and your books stay honest.

Delete an invoice

Created an invoice by mistake? On the web, open it, click the ⋯ (Actions) menu at the top right, then Delete. Admins and Managers can delete invoices by default. The mobile apps don't offer this yet.

An invoice can only be deleted while it has no payments recorded against it. Once money is attached, the option no longer appears, because the payment needs an invoice to belong to. Invoices synced to QuickBooks can't be deleted here either; delete them in QuickBooks first.

A deleted invoice disappears from your lists, and the link your client received stops working. This cannot be undone.

Tip

Want it out of the way but kept on file? Use Archive in the same menu instead. Archived invoices leave your lists and can be restored at any time, and you can still delete one later from its ⋯ menu.

Frequently Asked Questions

No. New invoices start as Unsent, which works the same way. You can edit freely until you send.
Yes. In the send window choose Text message (or Both) and check the client's Mobile number. The Text message box shows the text that goes out, with a secure link to the invoice; edit it if you like, and if you delete the link WorkZen adds it back at the end. Texting needs your company's default texting line, or the shared WorkZen number on ZenGrow and ZenAI. You can also click Share on the client-facing invoice to copy the link and deliver it any way you like.
If your company has Stripe connected, the invoice your client opens shows Pay with Card and, when enabled, Pay by Bank. Payments recorded this way update the invoice balance automatically.
Yes. Open the invoice and choose Void. A voided invoice is no longer payable and its totals are excluded from reports. If it has payments, refund or delete them first.
Yes, on the web, as long as no payments are recorded against it. Open it, click the ⋯ (Actions) menu, then Delete. Admins and Managers can delete invoices by default. An invoice with payments, or one synced to QuickBooks, cannot be deleted; archive it instead.
Creating and editing requires the Manage Invoices permission, and sending requires Send Invoices. Admins have both by default.
