Hi there,
QuickBooks is great when it comes to adding custom invoices which make your business stand out. I know how time-consuming it can be to deal with error messages and I'll be glad to help with that.
First, you'd have to investigate if the custom file you're uploading meets the criteria in this article here. The article also goes over steps on how you can map your custom invoices so they can seamlessly uploaded. When uploading file types, make sure to avoid the following files as they'll produce error messages:
- Audio
- ClipArt, Word Art
- Animated GIFS
- Embedded files
- Adding or updating hidden links or merging fields
- Files over 2MB
- Non-.docx file types or older MS Word documents renamed as .docx files
Once you've verified that the mapping is correct and you're still getting that error, I recommend contacting our support team using this link here. One of our agents will be happy to give you a hand and ensue you're able to upload your invoice with the account summary custom field.
Let me know if you have other questions. I'll be on standby. Otherwise, enjoy the rest of your week and stay safe!
