Custom Fillable PDF Invoice & Quote

I need two separate, professionally laid-out templates—a sales invoice and a quotation—delivered as fully fillable PDFs. Each file must open in Adobe Acrobat Reader (and similar viewers) with the ability to type, save, and email the completed form.

Core requirements
• Format: interactive PDF only (no Word or Excel versions).
• Mandatory fields: Customer information section, an itemized list of products or services with lines that can expand if needed, and an auto-summarised Total amount box.
• Branding: a placeholder for my company logo on the header; colour palette can stay neutral so I can tweak later.

Deliverables
- Invoice_template.pdf
- Quote_template.pdf

Both templates should share a consistent look, clear tab order, and locked layout so accidental edits to design elements are prevented. Once I drop the logo in, everything should be ready for immediate client use.
