Uncommon Giving vs Millie: A Side-by-Side Comparison

Both platforms serve small and mid-sized social impact teams, and both are well reviewed. The main differences are pricing transparency, fee structure, and disbursement speed. Both publish a starting price for workplace giving, but the structures differ: Millie prices per employee with modules added on top, while Uncommon Giving is a flat annual program fee that scales with workforce size rather than charging for seats. Uncommon Giving starts at $5,000 per year for employee giving and volunteering, publishes corporate grants at $2,400 per year, launches in 48 hours, disburses to nonprofits twice monthly with no minimum threshold, and takes 0% of grant dollars disbursed. Millie publishes a calculator for workplace giving that returns $18,262 per year at 500 employees for donations, volunteering and payroll, and publishes no grants price at all. Millie states a 3 to 4 week implementation and applies a $45 minimum disbursement threshold with funds arriving 15 to 45 days after that threshold is met. Millie publishes a larger headline database figure of 7M+, though it does not publish how many of those organizations are eligible to receive funds.

Millie publishes a working pricing calculator for workplace giving and volunteering, which is worth crediting because most of this category does not. Millie prices per employee. Run on 14 September 2026 with donations, volunteering and payroll selected, Millie's calculator returns $9,101 per year at 100 employees, $12,779 at 250, $18,262 at 500, $26,424 at 1,000, and $67,770 at 5,000. Donations on their own start at $8,491 for 100 employees, and payroll giving is a paid add-on rather than part of the base. Uncommon Giving is a flat annual program fee starting at $5,000 per year for employee giving and volunteering. It scales with the size of your workforce, but it is not a per-user price: you are not buying seats and you are not charged more when participation grows, which matters because driving participation is the entire point of the program. Corporate grants management is sold separately, published from $2,400 per year, and implementation starts at $0. Ask both vendors for a written quote at your own headcount, and check whether volunteering and payroll are inside the number or added to it.

Millie itself takes no portion of donations, which the company states clearly. The donation still carries fees. Millie's knowledge base documents a 1.5% Percent/Goodstack platform fee per donation, paid to their donor-advised fund partner, plus standard card processing fees charged by Stripe on top of that. Neither fee is capped. Uncommon Giving states its own rate directly: donations disbursed to nonprofits through employee giving carry a standard disbursement fee of 2%, capped at $100 per disbursement. The cap is the meaningful difference on larger gifts.

Millie's knowledge base states a $45 minimum disbursement threshold pooled across all Goodstack-connected platforms, not just Millie. Once a nonprofit crosses that threshold, funds typically arrive 15 to 45 days later. If the threshold is never reached, the payment processes after 365 days. Nonprofits onboarded through Goodstack receive ACH payments; others receive checks, or funds may be redirected to similar organizations. Uncommon Giving disburses twice monthly with no minimum payout threshold, so a small gift to a small local nonprofit moves on the same schedule as a large one.

Yes. Millie has a real grants module covering applications, document collection, reviewer assignment, approval workflows, budget management, fund disbursement, and reporting. This is genuine feature parity and it would be inaccurate to say otherwise. The difference is economic. Uncommon Giving publishes grants pricing starting at $2,400 per year and takes 0% of grant dollars disbursed, so 100% of every grant reaches the grantee. Millie publishes no grants price at all. Its pricing page carries a real calculator on the workplace giving tab, but the grant management tab has no calculator, only "Tell us about your grant program" and a Request Custom Proposal button. Grant dollars moving through Millie's donor-advised fund partner also carry the same 1.5% platform fee that applies to donations. See Uncommon Giving's grants management →

Millie publishes a 3 to 4 week implementation timeline in its own comparison table, and users on G2 report roughly one month on average. Uncommon Giving launches in 48 hours with self-serve configuration and implementation starting at $0. Both platforms charge no standard implementation fee, so the difference is time rather than cost. If you are trying to get a program live before a GivingTuesday or an open enrollment window, that gap is the whole decision.

Millie publishes three integrations: Slack, SSO with automatic provisioning, and Double the Donation. Microsoft Teams is listed as coming soon. No payroll or HRIS integration is published on Millie's site or in its knowledge base, and Millie's payroll giving documentation states that "your company will process deductions on the 5th of each month based on the elections made in Millie the prior month," which is a manual step for your payroll team each cycle. Uncommon Giving integrates with Paychex, Paylocity, Paycor, ADP, and UKG, with HRIS employee sync, SSO via SAML 2.0, Slack, and Idealist.

Less than you might expect, and it is worth being accurate about it. Both platforms give employees a funded account, and both also let an employee pay per donation by card without funding that account first. On Millie, wallet funds are held by its foundation partners, the Percent Impact Foundation in the United States and the Intelligent Foundation in the United Kingdom. On Uncommon Giving, the account is a DAF-backed giving account with no minimum balance, funded by payroll deduction, card, or employer contribution, where the tax deduction applies when money goes in and tax receipts generate automatically. Some Millie reviewers on Capterra describe the wallet as clunky or hard to reconcile, but that is a comment on the interface rather than a limit on how you are allowed to give. If this is a deciding factor for you, ask both vendors to demo a card donation and a wallet donation back to back.

Engagement design, clearly. Giving Madness, Millie's bracket-style giving tournament where employees vote on where corporate dollars go, has no Uncommon Giving equivalent, and Millie's 4.9 Capterra and 4.8 G2 ratings are earned. If a gamified tournament is the specific thing you are buying, that is a real reason to buy it. Two other Millie claims are often read as advantages but are harder to verify. Its 7M+ database figure is published without a methodology or a count of how many organizations can actually receive funds, and Millie describes the same figure as worldwide on one product page and as "registered 501c3 nonprofit organizations" on another. Its local currency support is published without a currency list, a country count, or any statement of what currency the nonprofit is paid in. Ask for specifics on both before treating either as decided.

Both rate well and neither has a credibility problem. Uncommon Giving holds a 4.9-star Capterra rating. Millie holds a 4.9-star Capterra rating and a 4.8-star G2 rating. Ratings alone will not decide this comparison. The recurring Millie criticisms in verified Capterra reviews cluster around the pre-funded wallet, reconciling wallet balances, finding local nonprofits in a large database, and uncertainty about whether donations reached their destination. Each of those maps to a design decision rather than a bug, which is why they are worth reading before choosing.

Based on Millie's published documentation and verified third-party reviews, the recurring reasons are: (1) Pricing structure: a flat annual program fee rather than a per-seat price with volunteering and payroll added on top, so a successful participation campaign does not raise the bill. (1b) Published grants pricing: $2,400 a year against a custom proposal, on a platform whose workplace giving tab returns a number in seconds. (2) Fee structure: a 2% disbursement fee capped at $100 is easier to defend to finance than a 1.5% uncapped partner fee stacked on card processing. (3) Disbursement speed: twice monthly with no threshold, against a $45 pooled minimum and a 15 to 45 day window. (4) Grants economics: 0% of grant dollars disbursed at a published $2,400 per year. (5) Payroll and HRIS: integrated deductions rather than a manual monthly process. (6) Speed to launch: 48 hours against 3 to 4 weeks.
