A buyer told you the deal needs SOC 2, you've never done one, and you searched for what to do - and the top results are all about "bridge letters." Here's the problem those pages don't mention: a bridge letter bridges from a SOC 2 report you already have to your next one. It presumes a prior report exists. If this is your first time, there is nothing to bridge from, and most of that advice quietly does not apply to you.
That confusion is the entire reason this page exists. Below are the options that do apply to a first-timer with a live deal - sorted by the one variable that actually decides between them: how fast the deal needs proof.
This guide is independent. GRC Migrate takes nothing from platform vendors or audit firms - no commissions, no partnerships. Our revenue comes from services partners, disclosed plainly. We don't sell SOC 2, so this page has no reason to rush you toward the most expensive version of it.

Why your search results are the wrong advice
Search "SOC 2 deal blocked" or "how to prove SOC 2 fast" and the results skew toward bridge letters and gap letters, because that content is written for the far more common situation: a company that has a report and needs to cover the window until the next one issues. You're in the rarer, more urgent spot - no report at all - and you need to know which mechanisms are genuinely open to you. There are three, and which one is right depends entirely on your deal's clock.

Deal needs proof this week → an auditor-issued comfort or engagement letter
The mechanism open to a first-timer under real time pressure is a comfort letter or engagement letter issued by an auditor. It confirms that a SOC 2 audit engagement has been scheduled or is underway. The critical distinction: this letter is issued by the auditor - it is not something you write and sign yourself, which is exactly what separates it from a bridge letter.
Set expectations honestly: acceptance varies by buyer. Some procurement teams will take an auditor's letter as interim evidence of good faith and keep the deal moving; others hard-require an actual report and won't substitute. Treat it as a way to buy time and signal seriousness, not a guaranteed unlock - and pair it with a dated plan for the real report behind it.
This requires engaging an auditor, which is a step in itself. If you don't have one yet, that's the first thing to sort out - and the personal read below can help you think through the sequence without selling you an introduction.
Deal can wait a few weeks → SOC 2 Type 1
A SOC 2 Type 1 report assesses whether your controls are designed appropriately at a single point in time. Crucially for a first-timer under pressure, it has no multi-month observation period - unlike Type 2, which watches controls operate over a window. That makes a Type 1 meaningfully faster to reach than a Type 2, which is why it's the standard interim move to un-stick a live deal while the longer report runs behind it.
Many sophisticated buyers treat a Type 1 as an interim signal rather than the destination - so plan on Type 2 following it. For what "designed appropriately" actually requires of you, and how the pieces cost out, see the SOC 2 decision guide and the true cost of SOC 2.
Deal has a real timeline → SOC 2 Type 2
A SOC 2 Type 2 covers an observation window - typically 6–12 months of evidence that your controls operated, not just that they were designed. It's what sophisticated enterprise buyers actually want, and if your deal genuinely has that runway, going straight to Type 2 (or Type 1 now with Type 2 immediately behind it) is the durable answer.
This is the point where it stops being a "prove it fast" problem and becomes a normal build-a-program decision. Rather than repeat it here: whether you need SOC 2 at all and how Type 1 and Type 2 sequence is on the decision page, and the full platform + audit + labor cost is broken down separately.
Why not a bridge letter?
Because a bridge letter needs a bridge to stand on. A bridge letter (or gap letter) is self-issued by the company - signed by an officer such as your CISO, CTO, or CFO, not by an auditor - and it covers the gap between the end of a prior SOC 2 report's period and the issuance of the next report, typically for a window of up to about 90 days. Every word of that presumes you already hold a SOC 2 report.
With no prior report, there is no period to bridge from, so a bridge letter simply isn't a document you can produce. The first-timer equivalent - a letter from an auditor confirming an engagement is underway - is a different instrument with a different signer, which is why the "just send a bridge letter" advice all over your search results leads nowhere for you.
