Marketing-sourced pipeline is a sourcing model, not an attribution model. Attribution answers which touches earned revenue credit. Sourcing answers a simpler question: did the opportunity exist because marketing started it, or because sales started it. Teams fight about this every quarter because the rules were never written down. This guide walks you through a two-week build that defines sourcing rules, draws a clean line between marketing-sourced and sales-sourced, assigns joint ownership to the CMO and RevOps lead, and gives you a defensible 40 to 60 percent sourced target for mid-market SaaS.
Time: 2 weeks
The first failure mode is conflating two different questions. Attribution asks which touches get revenue credit across a long buying journey, usually with a multi-touch model like W-shaped or linear. Sourcing asks a binary question at the moment the opportunity is created: did marketing originate this deal, or did sales. Sourcing uses one touch, almost always the first one associated with the primary contact on the opportunity. Attribution can split a dollar across five touches. Sourcing hands the whole opportunity to one team. Write that distinction at the top of the policy doc and get the CMO and RevOps lead to sign it before you argue about any specific rule.
The whole model lives or dies on a short list of rules anyone on the team can read and apply. The default pattern that holds up at most mid-market B2B SaaS companies looks like this: if the first touch is a marketing-owned action, the opportunity is marketing-sourced. If the first touch is an outbound sales action against a contact who had no prior marketing engagement, it is sales-sourced. Inbound-form fills, organic search, paid search, paid social, webinars, content downloads, event registrations, and chatbot conversions are marketing. Outbound cold calls, cold emails from an SDR sequence against a cold contact, and conference booth scans from a sales-run booth are sales. Partner and referral deals usually get their own third bucket so neither team claims them.
Sourcing is only as honest as the data model behind it. Every contact needs a first-touch source and first-touch timestamp that is set on creation and never overwritten. Every opportunity needs a primary contact and a sourced-by field that is calculated from that primary contact's first touch. Prior-engagement logic matters: an SDR who dials a contact who filled out a form six months ago is not creating a sales-sourced deal, because marketing already touched the record. Build a prior-engagement window (90 to 180 days is standard) and let the CRM resolve the sourced-by value automatically. Strkr CRM can hold first-touch, prior-engagement window, and the sourced-by calculation on the opportunity record so humans never have to pick the value.
Marketing-sourced pipeline that marketing both produces and grades is not credible, and sales will stop trusting the number inside a quarter. The CMO owns the demand strategy that produces sourced pipeline. RevOps owns the system of record that calculates it. Write that governance into the policy doc: marketing proposes rule changes, RevOps implements and audits them, and both leaders sign off before anything ships. Review the sourced-by field monthly in a joint CMO and RevOps meeting. Spot-check 10 to 20 opportunities each cycle and reclassify anything the rules misfired on. When the number is governed by two leaders with different incentives, the rest of the business trusts it.
A number without a target is a scoreboard nobody reads. For mid-market B2B SaaS with a mixed inbound and outbound motion, 40 to 60 percent marketing-sourced pipeline is a healthy band. Below 40 and marketing is a cost center that is not pulling its weight on demand. Above 60 and sales is probably not running enough outbound, which is a long-term risk because inbound alone rarely scales a company past series B. Pure product-led growth teams run higher, closer to 70 to 80 percent. Enterprise sales-led teams run lower, closer to 25 to 40 percent. Pick a target band for your motion, write it in the policy doc, and review it quarterly against actuals.
Build one report that shows sourced pipeline for the quarter, the running sourced percentage, the breakdown by channel inside marketing-sourced, and the breakdown by SDR or AE inside sales-sourced. Add a trailing-four-quarter trendline so a bad month does not panic the room. Put the report on a dashboard the CMO, head of sales, and CEO all open. Show opportunity count, pipeline dollars, and conversion-to-closed-won by sourced-by. Partner-sourced gets its own row so it is never argued about. The dashboard is the single answer when anyone asks 'how is marketing doing' and it keeps the quarterly conversation grounded in the same data.
Three edge cases produce most of the Monday-morning fights. ABM: marketing builds a target account list, an SDR works it. Rule: if the account was on a marketing-owned ABM list before the SDR dialed, it is marketing-sourced. Events: marketing runs the booth, sales staffs it, both scan badges. Rule: if the event was marketing-run and on the marketing calendar, scans are marketing-sourced regardless of who swiped the badge. Revived closed-lost: an old deal comes back after a marketing nurture campaign. Rule: if the primary contact had a marketing touch inside the prior-engagement window before the revival, it is marketing-sourced. Write every edge case into the policy doc and let the CRM apply the rule automatically.
Sourcing policy is not a one-time deliverable. Every quarter, pull the sourced report, pull the win rate by sourced-by, and pull the forecast for next quarter. If marketing-sourced win rate is persistently below sales-sourced, the sourcing rules are letting weak opportunities count. Tighten the inbound-form definition, raise the engagement window, or remove channels that are not producing qualified pipeline. If partner-sourced is quietly becoming the biggest bucket, build a partner demand plan and give it an owner. Treat the model like a product: versioned, reviewed in a joint CMO and RevOps session, and improved on a predictable cadence instead of ad hoc after a bad month.
A marketing-sourced pipeline model is a set of rules that classifies every new opportunity as either marketing-sourced, sales-sourced, or partner-sourced based on the first touch on the primary contact. It is a sourcing model, not an attribution model, and it hands the whole opportunity to one team instead of splitting credit.
Sourcing is binary and uses one touch, usually the first touch on the primary contact, to assign the whole opportunity to a team. Attribution splits revenue credit across many touches using a model like W-shaped or linear. Sourcing answers who started the deal. Attribution answers which touches earned revenue credit.
For mid-market B2B SaaS with a mixed inbound and outbound motion, 40 to 60 percent marketing-sourced pipeline is a healthy band. Product-led teams run higher, closer to 70 to 80 percent. Enterprise sales-led teams run lower, closer to 25 to 40 percent. Pick a band that fits your motion and defend it in the quarterly review.
Ownership is joint. The CMO owns the demand strategy that produces sourced pipeline. The RevOps lead owns the CRM system of record that calculates sourced-by. Rule changes require dual signoff. Shared ownership keeps the number credible because the leader who produces it is not the leader who grades it.
Only if the contact had a prior marketing touch inside the engagement window, typically 90 to 180 days before the call. If an SDR dials a cold contact with no marketing history, it is sales-sourced. If the SDR dials a contact who downloaded a whitepaper four months earlier, the deal is marketing-sourced because marketing originated the relationship.
Audit sourced-by values on recent opportunities monthly in a joint CMO and RevOps meeting. Review the full policy, win rate by sourced-by, and target band quarterly in the business review. Treat the model like code: versioned, dual-signed, and shipped with a short changelog so sales always knows what moved.
Strkr CRM holds first-touch, prior-engagement windows, and sourced-by on every opportunity so the CMO and RevOps lead report the same number without a spreadsheet war.
