How-to
How do I invoice many customers at once?
Quick answer
Create the invoices for the period, then select them all in the invoice list and send them in a single action rather than opening each one. In Daily Invoice Maker that is Invoices, Select All, then Email Invoices — one confirmation sends the whole batch, and the send runs offline-tolerant so a dropped connection does not lose the queue.
Most service businesses bill the same customers every month at the same rate. Doing that one invoice at a time is the single biggest time sink in a small operation — and the place where invoices get skipped entirely.
Step by step
Get your customers and rates on file first
Open Customers and make sure each recurring customer has their monthly rate saved. Bulk sending is only fast if the amounts are already known; if you retype rates each month you have not saved anything.
Create the period's invoices
Generate the invoices for the month or week you are billing. Because the rate lives on the customer record, each invoice comes out pre-filled and you are checking rather than typing.
Open Invoices and filter to what you are sending
Filter the list down to the batch you mean to send — the current month, or unsent invoices only. Sending is destructive to your inbox reputation if you catch the wrong rows, so narrow first.
Select All, then Email Invoices
Tick Select All at the top of the list and choose Email Invoices. You get one confirmation showing how many will go before anything is sent.
Watch the batch complete
The send reports progress per invoice rather than firing blindly, so you can see which ones went and which failed — a bad address in row 30 does not silently abort the other 39.
Use Change Status to mark the batch
After sending, select the same rows and use Change Status to set them all to Sent in one action, so your unpaid list stays meaningful.
What usually goes wrong
Sending before checking the list
The most common error is bulk-sending a filter you did not verify. Always narrow the list and read the count in the confirmation before approving it.
Rates not on the customer record
If rates live in your head, bulk billing just moves the typing rather than removing it. The saving comes from the customer record, not the send button.
No record of who was actually billed
Marking the batch's status after sending is what turns the invoice list into a usable record of who owes you. Skip it and you are back to guessing.

Questions
How many invoices can I send at once?
There is no fixed cap in the app; the practical limit is your email provider's sending rate. Batches in the dozens are routine for a monthly service route.
What happens if one email address is wrong?
That invoice fails and is reported; the rest of the batch continues. You fix the address and resend that one rather than repeating the whole batch.
Do I need internet to create the invoices?
No. Creating and storing invoices works fully offline — only the actual email send needs a connection. You can prepare the whole batch on the road and send when you have signal.
Can I do this on my phone?
The Android app covers the same invoicing workflow and is a separate Google Play purchase. The $149.95 licence covers Windows and Mac.
