What is a Pro Forma Invoice?

A SaaS pro forma invoice is an early-stage bill of sale that a software company sends to a customer before providing services or receiving payment. 

It connects informal software sales with formal enterprise purchasing by establishing commercial expectations at an initial stage.

For operations teams, differentiating the legal status of a pro forma document from official documents is a consideration. A pro forma invoice does not typically create a legal obligation for payment. This item is not classified as an account receivable within the supplier’s general ledger, nor is it recognized as a tax credit document for the buyer. On the contrary, it is a formal document that previews the intended transaction.

SaaS companies must provide documentation, including necessary operational variables, to maintain high billing efficiency and internal understanding. Each document must specifically feature the following entry:

• The obvious “Pro Forma Invoice” heading to mark it differently from the overall tax and financial liabilities.
• Detailed software components, subscription lengths, and main platform tiers.
• Calculated subtotal fees, applicable regional software discounts, and final expected prices.
• Intended payment terms should be accompanied by the most common payment methods of the platform.

A pro forma invoice is a document that outlines what a transaction would be like; it does not entail the legal or financial aspects of an enforceable accounting document, either. Since it occurs before transaction finalization, it does not represent a true financial buyer liability or an active receivable asset for the vendor. For enterprise buyers, this document is not applicable for the purpose of claiming regional input tax credits or digital service tax write-offs.

When operations teams choose to use this, they should opt for billing software running on a single platform to automate the making of these documents, rather than manually making the text template each time. The new revenue infrastructure envisages the platform creating these drafts when the enterprise deal state changes to negotiation or approval workflows. Automated billing generation is associated with data delivery from CRM platforms to the buyer’s procurement queue (independent of manual data input). ​‍​‌‍​‍‌​‍​‌‍​‍‌

Usually,​‍​‌‍​‍‌​‍​‌‍​‍‌ vendors are required to establish clear expiration frames, 14 to 30 days being the most common. Establishing a defined timeframe for offer validity addresses the software seller’s concerns regarding potential changes in base seat price, tier adjustments, or foreign currency exchange rates that may occur during extended enterprise negotiation processes.

These are some points to help determine whether your B2B software company should consider implementing a structured pre-billing workflow:

1. Is your enterprise audience target in need of formalized purchasing paperwork before granting spending authorization?
2. How do manual invoice adjustments, stemming from customer requests, affect your operational processes?

The introduction of this documentation workflow may lead to variations in operational clarity and efficiency, primarily for businesses with specific needs. It may be appropriate to evaluate the use of a pro forma invoice when the sales model involves substantial enterprise sales contracts, incorporates multi-tiered custom billing arrangements, or includes transactions with global buyers subject to international banking regulations.
