Purchasing can consume hours each week. Supplier quotes wait for review, purchase orders go unlogged, deliveries arrive late, and invoices do not match what was received.
I compared procurement options that small businesses can realistically use, including managed assistants, group purchasing organizations, and sourcing services.
Wing Assistant ranks first for day-to-day purchasing support, but the right choice depends on whether you need lower prices, reliable execution, or a formal sourcing process.

How I Tested These Procurement Services
Task coverage. I prioritized services that create and log POs, collect quotes, track deliveries, and help reconcile invoices.
Compatibility. I favored providers that can work in existing systems such as NetSuite, Coupa, SAP, and QuickBooks.
Cost. Published pricing received more weight, while unclear or project-based rates are labeled as starting prices or custom quotes.
Security and oversight. I considered access controls, stated certifications, task visibility, and whether supervised support was available.
Small-business fit. Each option offers an entry point for companies that do not have an internal procurement department.
1. Wing Assistant
Wing Assistant Pros
- Dedicated assistant for POs, quotes, and vendor follow-ups
- Handles purchase requisitions, PO logging, and quote comparisons
- Works in Coupa, SAP, NetSuite, and QuickBooks
- Wing states ISO 27001 and SOC 2 certifications
- Flexible month-to-month support that can scale with demand
- Real-time task visibility through the Wing Workspace app
- Part-time and full-time plans for easier piloting
Wing Assistant Cons
- Plans use monthly hour blocks
- Costs more than basic offshore marketplaces
- Your team must still define and manage final approval thresholds
My Experience with Wing Assistant
Most providers on this list address one part of purchasing. Wing covers the daily loop, from processing requisitions and logging POs to comparing quotes and following up with quiet suppliers.
If you want a dedicated procurement specialist to own POs, chase delayed shipments, and keep approvals moving, Wing was the most complete day-to-day option I reviewed. The same assistant remains assigned to the account, which is useful when vendor relationships, approval rules, and part numbers take time to learn.
Wing also fits into tools many small teams already use, so it does not require a separate procurement system. The Workspace app provides clear task visibility, while Wing states that purchasing data is protected through restricted, logged access. This combination of continuity, oversight, and flexible support makes Wing my first choice.
Wing Assistant Pricing
Wing lists procurement assistant plans at about $999 per month for 80 part-time hours and $1,599 per month for 160 full-time hours.
The part-time plan offers a practical starting point for a steady PO backlog. Confirm current pricing and scope directly, especially if you have multiple entities or specialized approval requirements.
2. Una
Una Pros
- Free membership with access to negotiated rates
- Includes a savings analysis
- Provides a dedicated account manager
- Covers common indirect purchasing categories
Una Cons
- Savings apply only to contracted categories
- Does not manage your internal PO workflow
- Results depend on your current supplier pricing
My Experience with Una
Una is a straightforward option if purchase prices are the main concern. Its group purchasing model gives members access to negotiated rates without requiring a new hire or major workflow change. The savings analysis also helps identify useful categories before you switch suppliers.
Una does not issue POs, chase deliveries, or match invoices. It works best alongside an employee or assistant who can handle those operational tasks.
Una Pricing
Membership is listed as free. Savings vary by category and your existing rates.
3. Sagedoer
Sagedoer Pros
- Low advertised hourly rates with a fully managed structure
- Free project manager supervision included
- Can be assigned to PO creation and vendor follow-up tasks
- Transparent, marked-up-free USD invoicing
Sagedoer Cons
- Not a dedicated procurement specialty; general VAs are assigned to purchasing tasks
- Working-hour overlap requires planning
- Approval and card rules must be documented
- Limited published security information
My Experience with Sagedoer
Sagedoer is an accessible entry point when budget is the main constraint. It does not offer a dedicated procurement role, but its general virtual assistants can be tasked with practical purchasing work, such as building purchase orders and following up on delayed shipments. Included project manager supervision provides an extra layer of oversight when supplier issues become complicated.
Clear controls are important. Document spending limits, approval thresholds, and escalation contacts before work begins.
Sagedoer Pricing
Sagedoer advertises rates from about $7 per hour part time and $6 per hour full time. Confirm current rates and minimum commitments when requesting a quote.
4. LBMC Procurement Solutions
LBMC Pros
- Covers buying, POs, master data, and AP support
- Offers a GPO with no listed membership fee
- LBMC cites average GPO savings of 10% to 25%
- Combines procurement advice with execution
LBMC Cons
- Pricing requires a custom quote
- Implementation is heavier than adding an assistant
My Experience with LBMC
LBMC suits businesses that view procurement as an ongoing function rather than a collection of tasks. It combines tactical buying, category support, and group purchasing under one provider. Its ability to connect PO management with accounts payable support may also help teams investigate invoice mismatches more consistently.
Expect a discovery process and a longer setup than you would have with a virtual assistant.
LBMC Pricing
Services are custom-quoted. LBMC lists no membership fee for its GPO, so ask for separate details if supplier savings are your priority.
5. Wishup
Wishup Pros
- Handles supplier vetting, POs, renewals, and invoices
- Supports vendor performance tracking
- Offers several tiers, including US-based assistance
Wishup Cons
- Plans are at the premium end of this list
- US-based support costs considerably more
- Fixed bundles provide limited billing flexibility
My Experience with Wishup
Wishup's vendor management scope is relevant to e-commerce and retail teams with many supplier relationships. Beyond creating POs, its assistants can maintain performance records and track renewals. That broader coverage is useful when supplier reliability matters as much as order processing.
The tradeoff is price. Teams needing only basic PO support may find a better-value option elsewhere.
Wishup Pricing
Wishup lists Prime at $1,999 per month, Elite at $2,999, and its US-based assistant plan at $5,400. Verify current plan details directly.
6. Prokur
Prokur Pros
- Supports RFx creation and supplier engagement
- Provides side-by-side scoring and audit trails
- Offers software tiers aimed at smaller teams
- Optional Concierge service can run sourcing events
Prokur Cons
- Concierge pricing is not published
- Software does not manage routine POs
- Internal approvers must remain involved
My Experience with Prokur
Prokur brings order to competitive bids that have outgrown spreadsheets. Its RFQ builder, structured responses, and supplier scoring create a clearer record of each sourcing decision. The audit trail is especially useful when partners, lenders, or managers ask why a supplier was selected.
Prokur structures sourcing decisions, but an employee or assistant must handle the follow-through.
Prokur Pricing
Software is listed from $249 to $399 per seat per month. The optional Concierge service requires a custom quote.
7. Dragon Sourcing
Dragon Sourcing Pros
- Identifies, evaluates, and negotiates with suppliers
- Supports onboarding, contracts, and quality assurance
- Useful when entering an unfamiliar supply category
Dragon Sourcing Cons
- Project timelines can be lengthy
- Pricing is quoted per engagement
- Not designed for routine purchasing administration
My Experience with Dragon Sourcing
Dragon Sourcing addresses the challenge of finding and qualifying suppliers rather than processing daily orders. That makes it relevant when importing goods, commissioning custom parts, or entering a category without an established network. Its scope extends through negotiation, onboarding, and quality checks.
Once suppliers are established, someone else will still need to manage POs, deliveries, and invoices.
Dragon Sourcing Pricing
Pricing is custom and project-based.
Conclusion
Wing Assistant is my top pick for most small businesses. It covers the daily purchasing cycle inside familiar tools while providing a dedicated assistant, visible task tracking, and flexible part-time or full-time support.
Una is the better starting point if negotiated supplier pricing is your priority, while Sagedoer offers lower-cost execution through general VAs assigned to purchasing tasks.
Consider LBMC for a managed procurement function, Prokur for structured RFQs, or Dragon Sourcing for building a supplier network.
Begin with a defined pilot, such as clearing a PO backlog and following up on delayed orders. Review accuracy, turnaround, and communication before expanding the scope.
