Salesforce staff augmentation adds a partner's specialists to your team under your direction. Project outsourcing hands a defined scope to a partner that directs the work and answers for the result. Managed services hand the ongoing running of your org to a partner for a monthly fee. Choose by who should manage the work and who should be accountable for the outcome.
All three are common for Salesforce, and many companies use more than one at once. This guide compares them side by side, sets out the risks of each and gives a short way to decide.
How do the three models compare?
The main differences are who directs the day-to-day work, who is accountable for the result, and how the work is priced. The table compares the three models on those points and on what each is best for.
| Question | Staff augmentation | Project outsourcing | Managed services |
|---|---|---|---|
| Who directs the work? | Your team lead or product owner | The partner's project manager, against an agreed scope | The partner, against agreed service levels and a backlog you prioritize |
| Who is accountable for the outcome? | You; the partner is accountable for the people's skills and availability | The partner, for delivering the scope | The partner, for the service levels in the contract |
| Cost model type | Time and materials, per person | Fixed price or time and materials for a defined scope | Recurring monthly fee for an allowance of hours or services |
| Who holds the knowledge? | Your team, if you document as you go | The partner during the project; handed over at the end | Shared, with runbooks and documentation kept by the partner |
| Best for | A team that owns its roadmap and needs more people or a missing skill | A defined build, such as an implementation, migration or integration, delivered by a date | Running and improving an org that is already live |
| Main risk | Management load and knowledge leaving with the people | Scope gaps and change requests | Low visibility of how hours are used |
When is staff augmentation the right choice?
Staff augmentation suits a team that already has a Salesforce owner, a backlog and a way of working, and needs more capacity or a skill it lacks. The added people join your stand-ups, use your tools and follow your standards. You keep control of priorities and design decisions.
Typical cases are a developer to clear a backlog, an architect for a design review or a new cloud, or an admin to cover a gap while you hire. It works best when someone on your side has the time and the knowledge to direct the work. If no one does, the extra people tend to wait for decisions, and you pay for that time.
See Salesforce staff augmentation for how we run it.
When is project outsourcing the right choice?
Project outsourcing suits work with a clear start, end and definition of done: a new implementation, a move from Classic to Lightning, a data migration or an integration. The partner plans the work, staffs it with the roles it needs and manages delivery. You own the requirements, decisions and acceptance.
The quality of the result depends on the quality of the scope. A fixed price moves delivery risk to the partner, but only for what the scope describes; anything missing becomes a change request. Spend time on discovery before you sign, and agree how changes will be priced and approved.
When are managed services the right choice?
Managed services suit an org that is live and needs to be run well: user and admin support, fixes, small enhancements, monitoring and preparing for each Salesforce release. Salesforce ships three major releases a year, in Spring, Summer and Winter, and the upgrades are mandatory, according to Salesforce Help. A managed services team tests your processes in the sandbox preview before each one.
The partner owns the org between requests, not only when a ticket arrives. You set priorities, usually through a shared backlog and a monthly review. See Salesforce managed services for what a contract usually covers.
What are the risks of each model, and how do you reduce them?
Each model fails in a predictable way. Most problems can be prevented in the contract and in the first weeks of the engagement.
| Model | Risk | How to reduce it |
|---|---|---|
| Staff augmentation | Your team spends more time managing than expected | Name a lead who directs the work; agree working hours and a weekly check-in |
| Staff augmentation | Knowledge leaves when a person rolls off | Make documentation part of the definition of done; agree a handover period |
| Staff augmentation | A person is not the right fit | Interview everyone; agree a replacement process and timescale in the contract |
| Project outsourcing | The scope misses requirements, leading to change requests | Fund a discovery phase; agree a written change process with pricing rules |
| Project outsourcing | A weak handover leaves you unable to support the result | Require documentation, admin training and a hypercare period in the scope |
| Managed services | Hours are used on low-value requests | Prioritize the backlog together; review hours and outcomes each month |
| Managed services | The team changes often and loses context | Ask for named core team members and notice of changes |
How do you decide which model fits?
Answer four questions in order. The first answer that is clear usually points to the right model.
- Is the work a defined project or an ongoing need? A defined build with an end date points to project outsourcing. Ongoing support for a live org points to managed services.
- Do you have someone who can direct Salesforce work every day? If yes, and you need more hands or a specific skill, staff augmentation is often the simplest choice. If no, choose a model where the partner manages delivery.
- Who should answer for the result? If you want the partner to be accountable for an outcome, staff augmentation is the wrong model, because it makes the partner accountable for people, not results.
- How predictable does the cost need to be? Fixed-price projects and monthly managed services fees are easier to budget. Time-and-materials augmentation is more flexible but depends on how well the time is used.
Many companies combine models: managed services to run the org, plus augmented specialists for a period when a larger change is under way, or a project team for a build followed by managed services after go-live.
What should you check before signing with any provider?
- The people. Interview the named team and check their certifications on Trailhead's credential verification page. Salesforce Help says certifications show there only if the holder's profile is public, so ask the person to share theirs.
- The partner's listing. Check the tier, rating and reviews on AppExchange yourself.
- Replacement and exit. How quickly a person can be replaced, how a handover works, and what documentation you keep if the contract ends.
- Access. Which Salesforce permissions each person needs, and how access is removed when they leave.
- Reporting. What you will see each week or month: work done, hours used and what comes next.

Frequently asked questions
What is the difference between Salesforce staff augmentation and outsourcing?
With staff augmentation you add a partner's Salesforce specialists to your own team and you direct their work. With project outsourcing you hand a defined scope to a partner, which directs the team and is accountable for delivering the result. The difference is who manages the work and who answers for the outcome.
Is managed services a type of outsourcing?
Yes, but for running an org rather than building something. In a managed services contract the partner supports and improves your Salesforce org on an ongoing basis, usually for a monthly fee covering a set allowance of hours or services, and is accountable for the service levels you agree.
Which model is cheapest for Salesforce work?
None is cheapest in every case. Staff augmentation is billed for time, so its cost depends on how well you manage the people. Fixed-price projects move delivery risk to the partner, which is priced in. Managed services spread cost across a monthly fee. Compare the total cost of the outcome you need, including your own management time.
Can we combine staff augmentation with managed services?
Yes, and many teams do. A common pattern is a managed services contract to run the org and handle releases, with augmented developers or architects added for a period when a larger change, such as a new cloud or integration, needs more capacity under your own lead.
How do we check the people offered through staff augmentation?
Interview each person, ask for a work sample or walk-through of past Salesforce work, and check their certifications on Trailhead's credential verification page. Agree in the contract how quickly a person can be replaced and who covers the handover if someone leaves.
