(1) A contract between a principal and a sales representative under which the sales representative is to solicit wholesale orders within this state must be in writing and must set forth the method by which the sales representative's commission is to be computed and paid. The principal shall provide the sales representative with a copy of the contract. A provision in the contract establishing venue for an action arising under the contract in a state other than this state, or establishing conditions for payment of a commission contrary to the provisions of this section, is void.
(2) When no written contract has been entered into, any agreement between a sales representative and a principal is deemed to incorporate the provisions of RCW
49.48.150 through
49.48.190.
(3)(a) During the course of the contract, a sales representative shall be paid the earned commission and all other moneys earned or payable in accordance with the agreed terms of the contract, but no later than thirty days after receipt of payment by the principal for products or goods sold on behalf of the principal by the sales representative.
(b) Upon termination of a contract, whether or not the agreement is in writing, all earned commissions due to the sales representative shall be paid within thirty days after receipt of payment by the principal for products or goods sold on behalf of the principal by the sales representative, including earned commissions not due when the contract is terminated.
(c) Where a sales representative's efforts prior to termination of a contract results in a sale, regardless of when the sale occurs, the termination may not affect whether a commission is considered earned.
(4) Failure to pay an earned commission is a wage payment violation under RCW
49.52.050.
